High end ultra-low power Panasonic PIR sensor module (12m range, 102° x 92° viewing angle, see detection performance chart) achieves high sensitivity (adjustable from app) and very low false alarm rate. The smallest wireless PIR sensor available in market today.  

Larger CR2450 battery provides 3x battery life compared with regular motion sensor Wireless Tags to reduce battery exchange labor. 2~3 year battery life is expected.
